D'ZEING-MACHINE.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed January 11, 1.91"?. Serial No. 141,729.

To all 'Lo/wm it may conce/rn:

Be it known that 1, llowaun lll. Donner, a citizen of the United States, and a residentl oit Philadelphia, in the county ot 'Philadelphia and State of Pennsylvania, hare invented certain new and usetul lmprore ments in Dyeing-Machines, ot which the following,I is a specilication.

My invention relates to a dyeing; `machine and refers particularly to a machine adapted tor the dyeing oi textile liliiers compimscd Within a dyeing;l chamber, the dyeingl being' accomplished by the toi-ced passage ot the dye liquor through the `ber mass.

Among the objects oli' my invention is a dyeing1 machine particularly suitable ttor the dyeing.;` ot n'arps lin the ball7 whereby the condition ot the liber may be accurately and readily judged at any stage ol the treatment Without opening` the dyeing chamber and whereby even results may be obtaiiied without disturbinp` the liber to be dyed.

Other objects o'i' my invention will be eri.- dent upon a consideration oit my specifications and claims. e

1 have found that the even or uneven dyeing results obtained in a machine ot this general character depend largely upon the particular shape ot the openings through which the dye liquor enters the iiber mass, and that unerenness can be prerentedby the use ot' openings ot a particular shapeT the conformation ol which enables the liquor to spread itseliE through the liber mass without the 'formation ot channels ot tion'.

1 have further tound that this desirable result can be obtained it the liber-mass is supported in the dyeing,l chamber upon thin strips ot' metal, or other suitable material. allowing,` an extreme amount ot openings t'or the passage ot the dye-liquor into the liber. 'tlhis result can be further augmented it the dye-liquor is toi-ced through passages prior to its introduction into the dyeing` chauiber.

The device oil my invention accoimplishes this in an inexpensive and effective manner.

Related forms ot my device are shown in the accompanying1 drawings, in which similar parts are designated by similar nunierals.

Figure 1 is a side View et one form oit my invention, partly broken avay to disclose a portion in cross-section- Fig. S2 is a cross-section through the line aL-2 oit Fifi'. 1.

Fig. 3 is a side vieu' oi one ot the supporting members in the bersupporting` plate.

Fig. Llis a side View oi one oi' the plates in, the liquor supply chamber.

iig. 5 is a side View of a modilication of one ot' the plates in the liquor supply chamber.

Fig'. ti is a side View oi a modiied i'orm oi' the supporting members in the fiber-supporting,- plate.

The outer portion oi the dyeing machine comprises the cylindrical shell i' and the cylindrical shell S, iixcdly attached to each other by the bolts i), 5); the conical shaped shell l0 liztedly attached to the shell Sby the bolts 11, 11 and the centrifugal pump 1:2 tixedly attached to the shell l() by the bolts 13, 13. iibersupporting plate 1li is situated between the shells 7 and 8 and comprises the annular' member l5 and a series of thin blades or supporting' members 1G` 1G parallel to each other and iixedly attached to the member l5. rfhese blades or supporting members are as thin as possible and e situated as far apart as possible to correctly hold the material to be dyed, while allowing' the maximum oit space 'for the passage ot the dye-liquor.

The machine is provided With a removable annular foran'iinous plate 17, the construction oit which is similar to the 'toraininous plate lll.

An annular angleshaped member 18, slidable Within the shell 7, capable oi abutment upon the plate 17 andmaintained in any desired position by means ot the thumbscrews 1S). 1S)` which thread within the shoub ders 20, '20 iiXedly attached to the shell 7.

El series ot plates 21. 2l are positioned in the interior portion of the shell l0, the plates extending across the chamber termed by the shell 10 and trom the top to the bottom thereof.

A second series oi' plates E22 are positioned in the chamber of the pump 12 in alincment with those Within the chamber oi the shell l0, although this series o't` plates may be omitted it' desired.

A perforated steam pipe Q5 is introduced into the chamber formed by the shell S.

lin order to Afacilitate reference to the various chambers, they will hereafter be referred to as the top chamber Q6, the dyeing chamber :27, the liquor supply chamber Q8, the plate chamber QSL and the pump chamber 30.

An overllow pipe 3l connects the top chamber :2G with a liquor reserve tanlr 4l, which is in turn connected to the ccntritu gal pump 1:3, by means oit the pipe i12 carry-` ing the Valve 43. i

A pipe connects toe pump l2, with a liquor supply tanlr, not shown, the pipe 39, carrying the if'alve t pipe 551i, este ds trom within the liquor supply` chamber 28 to a point above the top chamber 23, and carries a thermome ter .3b for regulating the temperature passA ing through the pipe 3ft,

A sample ,y ing machine 37, exactly similar to the obere described dyeing)` machine, except in smaller proportion connected to the liquor .supply chamber by the pipe 38 and to the top chamber 26 by the pipe 39. The sample material in the machine B7 is examined by removing the top -lll which is threaded to the sample machine 37.

Fig. 5 illustra les a serrated plate fla, a serios el which may replace the plates 2l, 2l, and liig, 6 illustrates a double serrated blade d5 which may replace the blades lG, lo.

The operation oli` the device is as follows:

The simular member l@ and the gtoraminous plate l? are removed, the goods to be treated introduced into the dyeing chamber 27, the plate l?" replaced and pressed Y down upon the goods by means ot the member 18. A small quantity of the same goods is placed in the sample device 37. The pump 1'2 is started and the Valve 33 opened, allowin the liquor to flow through the pipe 32 into the pump l2, by which it is forced upwardly through the pump chamber 30, the plate chamber 29, the liquor supply chamber 28, and the goods in the dyeing' cham ber 27, into the top member 26. When the liquor has reached the orer-tlow pipe 3l, it flows into the reserve tank il and from there through the pipe l2 into the pump l2 for continuous circulation. The object of the reserve tank al. is to allow oil' the production oli a larger quantity of dye-liquor than is necessary to fill the shells T. 8 and l0. By this means the strength of the dye-liquor may be governed to meet the requirements olf each individual dyeing operation, and the liquid maintained in a condition where the dye will not be precipitated upon the fiber, causing uneven results. It also allows a more uniform supply of liquor to the pump l2.

From time to time, the valve LA, is closed, the top all is removed Ytor the purpose of examining the condition of the dyeing operation and is then replaced and the valve `all opened. By this means the condition of the dyeing' operation in the dyeing,l chamber 27 may be judged without stopping the dyeing operation, or breaking oili a piece of the fiber contained therein.

It is evident that during this operation the nauseas i o1?" 1alates 22, and 2l, 2l, and through the spaces between the blades lo, lo, of the ri 3er-supporting` plate lll into the liber cou tained thereoiii, blades l6,'lt3, being so thin that they do not interfere with the uniform distribution of the dye-liquor through the liber. lis the plate ll" is the same as plate lll, the liquor pressure will be maintained within the dyeing chamber :fl/.

l do not limit mysellI to the size, shape, number or arrangement parts as shown and described, all oi which may be varied without going,l beyond the scope oli my in vention as described and claimed.
